As is well known, the 2nd Spanish Republic (1931-1936) was toppled by a military uprising which, after a cruel Civil War, set up an autocratic regime led by General Franco which lasted until his natural death in 1975. According to the contemporary theory of the legal system, a legal order exists on the sole condition that it is efficient in general terms and this was the case for both the Republic and the Dictatorship. In turn, the validity of the legal norms of all legal orders is based on its respective rules of recognition. Thus, neither the existence of the legal order nor the validity of its respective legal norms depends on moral considerations. In this paper, we call this affirmation into question on the base of the fact that the compensatory methods adopted from the Transition to Democracy show an evident concern to repair the damage of taking away a person’s basic rights (life, health, freedom, expression, association etc) although the Spanish Constitution, with its catalogue of fundamental rights was not in force at that time. But these measures would not have much sense if, as Raz says, there was no shared content which is common to all legal systems. Like Nino, we claim that one must discriminate between a democratic legal order and an autocratic one to establish the level of validity of its respective legal norms. Thus it can be assigned a presumption of justice to democratic norms. Finally, we state that the criteria to weigh up the justice or injustice of legal norms, as that of legal orders, takes root in the level of respect they show towards human rights.
Im späten Mittelalter setzt sich die deutsche Sprache immer stärker als Sprache der Medizin durch. Auch wenn deutschsprachige heilkundliche Werke jener Zeit vorrangig für Praktiker ohne akademische Ausbildung bestimmt waren und als Anweisungstexte gebraucht wurden, kann man darin schon Register und Inhaltsverzeichnisse finden, also solche Orientierungsmittel, die in der modernen Zeit zum festen Bestandteil von Fachtexten wurden. Diese Mittel der Textoptimierung unterscheiden sich zwar von den heutigen noch stark, nichtsdestoweniger zeugen sie davon, dass die Autoren deutscher medizinischer Werke ihre Adressaten vor Augen hatten und bemüht waren, ihnen die Rezeption des Fachwissens zu erleichtern.
In reconsideration of the composition and operation of European law, it is the description of its underlying mentality that may cast best light on the query whether European law is the extension of domestic laws or a sui generis product. As to its action, European law is destructive upon the survival of traditions of legal positivism, for it recalls post modern clichés rather. Like a solar system with planets, it is two-centred from the beginning, commissioning both implementation and judicial check to member states. As part of global post modernism, a) European law stems from artificial reality construction freed from particular historical experience and, indeed, anything given hic et nunc. By its operation, b) it dynamises large structures and sets in motion that what is chaos itself. It is owing to reconstructive human intent solely that any outcome can at all be seen as fitting to some ideal of order, albeit neither operation nor daily management strives for implementing any systemicity. This is the way in which the European law becomes adequate reflection of the underlying (macro) economic basis, which it is to serve as superstructure. Accordingly, c) the entire construct is operated (as integrated into one well-working unit) within the framework of an artificially animated dynamism. With its “order out of chaos” philosophy it assures member states’ standing involvement and competition, achieving a flexibly self-adapting (and unprecedentedly high degree of) conformity.
Accelerator Driven Systems (ADS) are promising tools for the efficient transmutation of nuclear waste products in dedicated industrial installations, called transmuters. The Myrrha project at Mol, Belgium, placed itself on the path towards these applications with a multipurpose and versatile system based on a liquid PbBi (LBE) cooled fast reactor (80 MWth) which may be operated in both critical and subcritical modes. In the latter case the core is fed by spallation neutrons obtained from a 600 MeV proton beam hitting the LBE coolant/target. The accelerator providing this beam is a high intensity CW superconducting linac which is laid out for the highest achievable reliability. The combination of a parallel redundant and of a fault tolerant scheme should allow obtaining an MTBF value in excess of 250 hours that is required for optimal integrity and successful operation of the ADS. Myrrha is expected to be operational in 2023. The forthcoming 4-year period is fully dedicated to R&D activities, and in the field of the accelerator they are strongly focused on the reliability aspects and on the proper shaping of the beam trip spectrum.
This paper examines the well-known practice of developing a conceptual frame-work for reading works of literature in such a way as to illuminate previously ignored aspects of those works. It investigates the nature or genre of such discoveries: Are they philological? Hermeneutic? Do they correspond to the discipline of the framework selected? This problem is considered in the case of an example of the deployment of a very specific philosophical framework, namely the problem of skepticism as glossed by the American philosopher Stanley Cavell. This framework brings to light a structural affinity between two seemingly disparate moments in the history of German lyric poetry: the Biedermeier period and the works of Konkrete Dichtung from the mid-twentieth century. The paper postulates this affinity as an exam-ple of the kind of “discovery” whose type, usefulness, or even existence as discovery might be called into question and perhaps not, ultimately, agreed on.
Partizipien und Adjektive gehören zu Sprachmitteln, die bei der Personendarstellung zur Beschreibung des Äußeren, der Interessen und der geistigen Welt in spezifischen Textsorten (hier: in Kontaktanzeigen lesbischer Frauen im Alter über 50 Jahre) verwendet werden. Im Vergleich zum Adjektiv kann das Partizip die zeitliche Dimension einer Eigenschaft oder der Lebenserfahrung ausdrücken; auf diese Weise können Sprechende den Wert der jeweiligen Eigenschaft oder Lebenserfahrung hervorheben. Das Partizip wird in bestimmten Kontexten bevorzugt, denn es kann die persuasive und appellative Funktion des Textes intensivieren. Die Autorin dieses Beitrags analysiert Motive und Strategien des Partizip-Usus' aus pragmalinguistischer Perspektive in 100 Kontaktanzeigen in der deutschen Frauenzeitschrift 'EMMA'.
Hybrid robust deep and shallow semantic processing for creativity support in document production
(2004)
The research performed in the DeepThought project (http://www.project-deepthought.net) aims at demonstrating the potential of deep linguistic processing if added to existing shallow methods that ensure robustness. Classical information retrieval is extended by high precision concept indexing and relation detection. We use this approach to demonstrate the feasibility of three ambitious applications, one of which is a tool for creativity support in document production and collective brainstorming. This application is described in detail in this paper. Common to all three applications, and the basis for their development is a platform for integrated linguistic processing. This platform is based on a generic software architecture that combines multiple NLP components and on robust minimal recursive semantics (RMRS) as a uniform representation language.
In this article, I examine how open borders can serve the idea of global distributive justice by asking how or how not the existing practices of immigration to rich countries may contribute to global economic redistribution. There are two observations. First, migration is not the redistributive option that anyone has an equal access. In order to make use of migration as a means of global redistribution, rich countries need to provide a chance to migrate to those who cannot afford movement by themselves. Second, as long as brain-drain problems happen, what the perspective of global distributive justice requires is the compensation for some educational cost of raising professionals or some control of their movement. Immigration admissions largely focusing on getting highly skilled professionals may not serve the idea of global redistribution.
University 2.0
(2007)
The major challenge facing universities in the next decade is to reinvent themselves as information organizations. Universities are, at their core, organizations that cultivate knowledge, seeking both to create new knowledge and to preserve and convey existing knowledge, but they are remarkably inefficient and therefore ineffective in the way that they leverage their own information resources to advance that core activity. This talk will explore ways that the university could learn from what is now widely called "Web 2.0" -- a term that is meant to identify a shift in emphasis from the computer as platform to the network as platform, from hardware to data, from the wisdom of the expert to the wisdom of crowds, and from fixity to remixability.
We present and compare new types of algorithms for lattice QCD with staggered fermions in the limit of infinite gauge coupling. These algorithms are formulated on a discrete spatial lattice but with continuous Euclidean time. They make use of the exact Hamiltonian, with the inverse temperature beta as the only input parameter. This formulation turns out to be analogous to that of a quantum spin system. The sign problem is completely absent, at zero and non-zero baryon density. We compare the performance of a continuous-time worm algorithm and of a Stochastic Series Expansion algorithm (SSE), which operates on equivalence classes of time-ordered interactions. Finally, we apply the SSE algorithm to a first exploratory study of two-flavor strong coupling lattice QCD, which is manageable in the Hamiltonian formulation because the sign problem can be controlled.
We discuss the implementation and results of a recently developed microscopic method for calculating ion-ion interaction potentials and fusion cross-sections. The method uses the TDHF evolution to obtain the instantaneous many-body collective state using a density constraint. The ion-ion potential as well as the coordinate dependent mass are calculated from these states. The method fully accounts for the dynamical processes present in the TDHF time-evolution and provides a parameter-free way of calculating fusion cross-sections.
Kategorien wie "nationales" oder "europäisches" Kulturerbe sind [...] nicht selbsterklärend. Immer aber werden sie mit großen Ansprüchen verbunden, sollen "Identität" stiften, zivilgesellschaftliche Normen beglaubigen oder den Bürgern eines bestimmten Landes dessen kulturelle und politische Bedeutung suggerieren. Touristisch vermarktet werden dabei zumeist die ästhetisch ansprechenden, politisch korrekten, also eher die unproblematischen und kulturell angenehmen Überlieferungen. Die negativen Seiten der Geschichte, die verstörenden Ereignisse der Vergangenheit und die Traumata der individuellen wie kollektiven Biographie sperren sich eher gegen eine glatte Nutzung im kulturtouristischen und ökonomischen Sinne. Mit ihnen kann man sich professionell in der Abgeschiedenheit von Akademien und Universitäten leichter beschäftigen als im Streit der öffentlichen Meinungen oder im Kontext touristischer Event-Kultur. [...] Die Tourismusindustrie und deren Werbung setzen immer wieder auf die Beschwörung der Präsenz längst gestorbener Geister. So behauptet beispielsweise das diesjährige Prospekt der "Thüringer Tourismus GmbH" mit dem saisonal bedingten Titel "Schiller lockt", dieser "klassische" Autor sei noch heute an den Stätten seines ehemaligen Wirkens "präsent". [...] In dem vor einigen Jahren erschienenen Sammelwerk "Deutsche Erinnerungsorte" steht auch ein Artikel über "Schiller" [...] Doch wird dort festgestellt, dass Schiller heute kein "deutscher Erinnerungsort" mehr sei, sondern ein Fall für Spezialisten und ein lebendiger Autor für allenfalls einige Hunderttausend Bundesbürger, die regelmäßig ins Theater gehen und dort ab und zu auch ein Stück von Schiller sehen. [...] Die Diskrepanz zwischen der nüchtern, wissenschaftlich konstatierten Bedeutungslosigkeit eines Dichters für das nationale Selbstverständnis der Nation und der emphatischen Behauptung der Tourismusbranche, der Autor sei bis heute präsent, verweist auf spezifische Probleme und Widersprüchlichkeiten im Umgang mit dem kulturellen Erbe, denen ich mich [...] etwas genauer zuwenden möchte, und zwar am Weimarer Beispiel.
The bare life and (the) modern law : a journey to some key concepts or conceptions of Agamben
(2012)
This text is imitating a journey which tries to explore what is completely unknown. It starts Homo Sacer and traces some key concepts namely der Muselmann, bare life, state of exception, sovereignty and nihilism in law. Doing so, it hopes to reach a general picture of biopolitics or biopower according to Agamben. So, first part of this text generally tries to clarify some fundamental concepts or conceptions in order to use them for its aim. The second part suggests an alternative reading of Agamben, centered around his concept of der Muselmann which is the ultimate figure defined by Primo Levi and Agamben chooses the term because of its resemblance to or representation of Homo Sacer. Der Muselmann was a derogatory term in its origin and very meaning has still been unclear today. So, the second part tries to clarify the meaning of der Muselmann (and unbaptized babies) from a different outlook, not from outside but inside of the referred concept. It tries to show a Muslim’s image of a non Muslim world in order to reveal what are the very meanings of sovereignty, law and biopolitics. So at the end of the journey, this text hopes to reach a different picture of modern life and a modern law.
Gedächtnis und Erinnerung sind für die Herausbildung kultureller Identitäten von entscheidender Bedeutung. Das gilt für Gesellschaften genauso wie für den einzelnen Menschen. Ohne das Wissen um die eigene Geschichte ist man im Gestrüpp der Gegenwart verloren. ‚Wo komme ich her‘ ist eine der Leitfragen menschlichen Existierens. Blicken wir zurück, orientieren wir uns an Fotographien, Briefen, Dokumenten, Zeugnissen, Gegenständen. Neben den schriftlichen Spuren geben uns aber auch Geschichten, Erinnerungen und Erfahrungen Anhaltspunkte bei der Dechiffrierung der eigenen Geschichte. Doch wer kann uns bei der Spurensuche unterstützen, wenn die eigenen Erinnerungen lückenhaft sind oder gar versagen? Im Informationszeitalter sind wir zwar über Mobiltelefon, Internet und Satelitenschüssel mit der ganzen Welt vernetzt und können aus einer Unmenge von Informationen auswählen, verlieren dabei aber leicht den Überblick, was fundiert ist und was nicht. Den Archiven und Literaturarchiven wächst dabei eine besondere Aufgabe zu. Denn sie verfügen über die Ressourcen, um Gedächtnis und Erinnern auf eine sichere Basis zu stellen.
Previous study showed that kaffir lime leaf contains alkaloid, flavonoid, terpenoid, tannin and saponin. The objective of this study was to examine the cytotoxic effect of kaffir lime leaf extract on cervical cancer and neuroblastoma cell lines. The method used for this research to determine cell viability was an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Results showed that an ethyl acetate extract had an IC50 for HeLa cells, UKF-NB3, IMR-5 and SK-N-AS parental cells of 40.7 μg · mL–1, 28.4 μg · mL–1, 14.1 μg · mL–1, and 25.2 μg · mL–1 respectively. Furthermore, the IC50 of chloroform extracts for HeLa cells, UKF-NB3, IMR-5 and SK-N-AS parental were 17.6 μg · mL–1, 18.9 μg · mL–1, 6.4 μg · mL–1, and 9.4 μg · mL–1 respectively. These data showed that kaffir lime extract reduces the viability of cervical and neuroblastoma cell lines and may have potential as anti-cancer compounds.
Two generic mechanisms for emergence of direction selectivity coexist in recurrent neural networks
(2013)
Poster presentation: Twenty Second Annual Computational Neuroscience Meeting: CNS*2013. Paris, France. 13-18 July 2013.
In the mammalian visual cortex, the time-averaged response of many neurons is maximal for stimuli moving in a particular direction. Such a direction selective response is not found in LGN, upstream of the visual processing pathway, suggesting that cortical networks play a strong role in the generation of direction selectivity. Here we investigate the mechanisms for the emergence of direction selectivity in the recurrent networks of nonlinear firing rate neurons in layer 4 of V1 receiving the input from LGN. In the model the LGN inputs are characterized by different receptive field positions, and their relative temporal phase shifts are reversed for the stimuli moving in the opposite direction. We propose that two distinct mechanisms result in the neuronal direction selective response in these recurrent networks. The first one is a result of nonlinear feed-forward summation of several time-shifted inputs. The second mechanism is based on the competition between neurons for firing in a winner-take-all regime. Both mechanisms rely on inhibitory interactions in the connectivity matrix of lateral connections, but the second one involves inhibitory loops. Typically, the first mechanism results in lower selectivity values than the second, but the time-course of acquiring direction selective response is faster for the first mechanism. Importantly, the two mechanisms have different input frequency tuning. The first mechanism, based on the nonlinear summation, result in a relatively narrow tuning curve around the preferred frequency of the stimulus in the case of the moving grating. In contrast, the direction selectivity arising from the second mechanism depends only weakly on the input frequency, i.e. has a broader tuning curve. These differences allow us to provide the recipe for identifying in experiment which of the two mechanisms is used by a given direction selective neuron. We then analyze how the statistics of the connections in the random recurrent networks affect the relative contributions from these two mechanisms and determine the distributions of the direction selectivity values. We identify the motifs in the connectivity matrix, which are required for each mechanism and show that the minimal conditions for both mechanisms are met in a very broad set of random recurrent networks with sufficiently strong inhibitory connections. Thus, we propose that these mechanisms coexist in generic recurrent networks with inhibition. Our results may account for the recent experimental observations that direction selectivity is present in dark-reared mice and ferrets [1,2]. It can also explain the emergence of direction selectivity in species lacking a spatially organized direction selectivity map.
Poster presentation at The Twenty Third Annual Computational Neuroscience Meeting: CNS*2014 Québec City, Canada. 26-31 July 2014: We study random strongly heterogeneous recurrent networks of firing rate neurons, introducing the notion of cohorts: groups of co-active neurons, who compete for firing with one another and whose presence depends sensitively on the structure of the input. The identities of neurons recruited to and dropped from an active cohort changes smoothly with varying input features. We search for network parameter regimes in which the activation of cohorts is robust yet easily switchable by the external input and which exhibit large repertoires of different cohorts. We apply these networks to model the emergence of orientation and direction selectivity in visual cortex. We feed these random networks with a set of harmonic inputs that vary across neurons only in their temporal phase, mimicking the feedforward drive due to a moving grating stimulus. The relationship between the phases that carries the information about the orientation of the stimulus determines which cohort of neurons is activated. As a result the individual neurons acquire non-monotonic orientation tuning curves which are characterized by high orientation and direction selectivity. This mechanism of emergence for direction selectivity differs from the classical motion detector scheme, which is based on the nonlinear summation of the time-shifted inputs. In our model these two mechanisms coexist in the same network, but can be distinguished by their different frequency and contrast dependences. In general, the mechanism we are studying here converts temporal phase sequence into population activity and could therefore be used to extract and represent also various other relevant stimulus features.
Privacy and its protection is an important part of the culture in the USA and Europe. Literature in this field lacks empirical data from Japan. Thus, it is difficult– especially for foreign researchers – to understand the situation in Japan. To get a deeper understanding we examined the perception of a topic that is closely related to privacy: the perceived benefits of sharing data and the willingness to share in respect to the benefits for oneself, others and companies. We found a significant impact of the gender to each of the six analysed constructs.
Background: Undergoing systemic inflammation, the innate immune system releases excessive proinflammatory mediators, which finally can lead to organ failure. Pattern recognition receptors (PRRs), such as Toll-like receptors (TLRs) and NOD-like receptors (NLRs), form the interface between bacterial and viral toxins and innate immunity. During sepsis, patients with diagnosed adrenal gland insufficiency are at high risk of developing a multiorgan dysfunction syndrome, which dramatically increases the risk of mortality. To date, little is known about the mechanisms leading to adrenal dysfunction under septic conditions. Here, we investigated the sepsis-related activation of the PRRs, cell inflammation, and apoptosis within adrenal glands.
Methods: Two sepsis models were performed: the polymicrobial sepsis model (caecal ligation and puncture (CLP)) and the LTA-induced intoxication model. All experiments received institutional approval by the Regierungspräsidium Darmstadt. CLP was performed as previously described [1], wherein one-third of the caecum was ligated and punctured with a 20-gauge needle. For LTA-induced systemic inflammation, TLR2 knockout (TLR2-/-) and WT mice were injected intraperitoneally with pure LTA (pLTA; 1 mg/kg) or PBS for 2 hours. To detect potential direct adrenal dysfunction, mice were additionally injected with adrenocorticotropic hormone (ACTH; 100 μg/kg) 1 hour after pLTA or PBS. Adrenals and plasma samples were taken. Gene expressions in the adrenals (rt-PCR), cytokine release (multiplex assay), and the apoptosis rate (TUNEL assay) within the adrenals were determined.
Results: In both models, adrenals showed increased mRNA expression of TLR2 and TLR4, various NLRs, cytokines as well as inflammasome components, NADPH oxidase subunits, and nitric oxide synthases (data not shown). In WT mice, ACTH alone had no effect on inflammation, while pLTA or pLTA/ACTH administration showed increased levels of the cytokines IL-1β, IL-6, and TNFα. TLR2-/- mice indicated no response as expected (Figure 1, left). Interestingly, surviving CLP mice showed no inflammatory adrenal response, whereas nonsurvivors had elevated cytokine levels (Figure 1, right). Additionally, we identified a marked increase in apoptosis of both chromaffin and steroid-producing cells in adrenal glands obtained from mice with sepsis as compared with their controls (Figure 2).

Conclusion: Taken together, sepsis-induced activation of the PRRs may contribute to adrenal impairment by enhancing tissue inflammation, oxidative stress and culminate in cellular apoptosis, while mortality seems to be associated with adrenal inflammation.
We describe two independent frameworks which provide unambiguous determinations of the deconfinement and the decoupling conditions of a relativistic gas at finite temperature. First, we use the Polyakov-Nambu-Jona–Lasinio model to compute meson and baryon masses at finite temperature and determine their melting temperature as a function of their strangeness content. Second, we analyze a simple expanding gas within a Friedmann-Robertson-Walker metric, which admits a well-defined decoupling mechanism. We examine the decoupling time as a function of the particle mass and cross section. We find evidences of an inherent dependence of the hadronization and freeze-out conditions on flavor, and on mass and cross section, respectively.
We study the implications on compact star properties of a soft nuclear equation of state determined from kaon production at subthreshold energies in heavy-ion collisions. On one hand, we apply these results to study radii and moments of inertia of light neutron stars. Heavy-ion data provides constraints on nuclear matter at densities relevant for those stars and, in particular, to the density dependence of the symmetry energy of nuclear matter. On the other hand, we derive a limit for the highest allowed neutron star mass of three solar masses. For that purpouse, we use the information on the nucleon potential obtained from the analysis of the heavy-ion data combined with causality on the nuclear equation of state.
The archaeological data dealt with in our database solution Antike Fundmünzen in Europa (AFE), which records finds of ancient coins, is entered by humans. Based on the Linked Open Data (LOD) approach, we link our data to Nomisma.org concepts, as well as to other resources like Online Coins of the Roman Empire (OCRE). Since information such as denomination, material, etc. is recorded for each single coin, this information should be identical for coins of the same type. Unfortunately, this is not always the case, mostly due to human errors. Based on rules that we implemented, we were able to make use of this redundant information in order to detect possible errors within AFE, and were even able to correct errors in Nomimsa.org. However, the approach had the weakness that it was necessary to transform the data into an internal data model. In a second step, we therefore developed our rules within the Linked Open Data world. The rules can now be applied to datasets following the Nomisma. org modelling approach, as we demonstrated with data held by Corpus Nummorum Thracorum (CNT). We believe that the use of methods like this to increase the data quality of individual databases, as well as across different data sources and up to the higher levels of OCRE and Nomisma.org, is mandatory in order to increase trust in them.
Principles can be directly expressed by law or may be found in jurisprudence, philosophy or literature. Often the principles are contradictory, as in the case of transparency and the taboo of state information disclosure. At the individual level, transparency and taboo, the sense and purpose of privacy may compliment each other. Moreover the rise of cyberspace has blurred the distinction between privacy and public. The taboo is widening. The development of the internet and of the social networks can alter the once apparently stable legal situation, bringing a new dynamic into play in both state and individual spheres. In the context of the internet it is as though the secret workings of the state are projected on its "walls and facades", reminding us of Plato's "Myth of the Cave". As Plato described, disillusionment and reflexive defensiveness can follow.
Die Kognitionswissenschaften studieren Themen wie Gedächtnis, Problemlösen, Sprache, Wahrnehmung, Aufmerksamkeit und nicht zuletzt den Willen des Menschen. Dies alles sind Untersuchungsfelder, die auch für die Rhetorik von zentralem Interesse sind. Ich möchte in meinem Vortrag vorstellen, wie man einige der wichtigsten Gegenstände vor allem der kognitiven Linguistik für rhetorische Analysen fruchtbar machen könnte – im Sinne einer kognitiven Rhetorik, einer Neuformulierung rhetorischer Problemfelder auf der Grundlage einer zeitgemäßen theoretischen Basis. Aus Zeitgründen werde ich mich auf zwei Felder konzentrieren, auf die conceptual metaphor-Theory George Lakoffs und Mark Johnsons und auf die Theorie der sogenannten "Frames". Weitere Kapitel aus der kognitiven Rhetorik könnten an die conceptual blending-Theorie von Mark Turner und Gilles Fauconnier anknüpfen, oder auch an die Kognitive Syntax eines Ronald Langacker, dessen syntaktisches Ikonizitätsprinzip eine Verbindung zwischen syntaktischer Gestalt und Ausdruckskraft eines Satzes herzustellen vermag. Diese beiden Theorien seien nur genannt. Am Schluss werde ich noch klären wozu wir das als Rhetoriker alles brauchen können.
Oral e-Poster Presentations - Booth 2: Spine 1 (Trauma&Misc), September 25, 2023, 10:00 AM - 10:40 AM
Background: Spondylodiscitis is a prevalent type of spinal infection, with pyogenic spondylodiscitis being the most common subtype. While antibiotic therapy is the standard treatment, some argue that early surgery can aid in infection clearance, improve survival rates, and prevent long-term complications such as deformities. However, others view early surgery as excessively risky. Due to the high mortality rate of up to 20%, it is crucial to determine the most effective treatment.
Methods: The primary objective of this study was to compare the mortality rate, relapse rate, and length of hospital stay for conservative and early surgical treatments of pyogenic spondylodiscitis, including determinants of outcomes. The study was registered on PROSPERO with the registration number CRD42022312573. The databases MEDLINE, Embase, Scopus, PubMed, and JSTOR were searched for original studies comparing conservative and early surgical treatments of pyogenic spondylodiscitis. The included studies were assessed using the ROBINS-1 tool, and eligible studies were evaluated using meta-analyses, influence, and regression analyses.
Results: The systematic review included 31 studies. The meta-analysis, which had a pooled sample size of 10,954 patients from 21 studies, found that the pooled mortality rate among patients treated with early surgery was 8%, while the rate was 13% for patients treated conservatively. The mean proportion of relapse/failure was 15% for patients treated with early surgery and 21% for those treated conservatively. Furthermore, the analysis concluded that early surgical treatment is associated with a 40% and 39% risk reduction in relapse/failure and mortality rates, respectively, when compared to conservative management. Additionally, early surgical treatment resulted in a 7.75-day reduction in length of hospital stay per patient (p<0.01). The most highly significant predictors of treatment outcome were found to be intravenous drug use, diabetes, the presence of an epidural abscess, positive cultures, location of infection, and age (p<0.001).
Conclusions: Overall, early surgical management was found to be consistently significantly more effective than conservative management in terms of relapse/failure and mortality rates when treating pyogenic spondylodiscitis, particularly for non-spinal epidural abscess spondylodiscitis.
In the current globalization debate the law appears to be entangled in economic and political developments which move into a new dimension of depoliticization, de-centralization and de-individualization. For all the correct observations in detail, though, this debate is bringing about a drastic (polit)economic reduction of the role of law in the globalization process that I wish to challenge in this paper. Here one has to take on Wallerstein’s misconception of “worldwide economies” according to which the formation of the global society is seen as a basically economic process. Autonomous globalization processes in other social spheres running parallel to economic globalization need to be taken seriously. In protest against such (polit)economic reductionism several strands of the debate, among them the neo-institutionalist theory of “global culture”, post-modern concepts of global legal pluralism, systems theory studies of differentiated global society and various versions of “global civil society” have shaped a concept of a polycentric globalization. From these angles the remarkable multiplicity of the world society, in which tendencies to re-politicization, re-regionalization and re-individualization are becoming visible at the same time, becomes evident. I shall contrast two current theses on the globalization of law with two less current counter-theses: First thesis: globalization is relevant for law because the emergence of global markets undermines the control potential of national policy, and therefore also the chances of legal regulation. First counter-thesis: globalization produces a set of problems intrinsic to law itself, consisting in a change to the dominant lawmaking processes. Second thesis: globalization means that the law institutionalizes the worldwide shift in power from governmental actors to economic actors. Second counter-thesis: globalization means that the law has a chance of contributing to a dual constitution of autonomous sectors of world society.
Poster Einleitung Im Rahmen effizienzsteigernder Maßnahmen sind klinische Behandlungspfade unter DRG- Bedingungen und im Rahmen der Qualitätssicherung wichtige Instrumente. Material und Methoden Aus der Analyse zweier erfahrungsbasierter klinischer Behandlungspfade in Frankfurt/D und Newcastle/GB wurde ein halbstandardisierter clinical pathway Carotisstenose entwickelt, der der heterogenen Befundkonstellation bei Aufnahme, den unterschiedlichen klinischen Stadien der Erkrankung und den individuellen Patientenbedürfnissen Rechnung trägt. Es wurden dazu zwei Gruppen mit je 25 konsekutiv in Frankfurt/D ( Gruppe FrankfurtI) und New Castle/GB ( Gruppe New Castle )operierten Patienten retrospektiv analysiert.Aus den retrospektiv erhobenen Daten wurde ein stadienbezogener und der Zuweisersituation gerecht werdender klinischer Behandlungspfad erstellt, der anhand von 20 konsekutiv operierten Patienten, davon 60 % im Stadium IV der Erkrankung, ( Gruppe FrankfurtII ) analysiert wurde. Ergebnisse In Frankfurt 1 wurde 21 mal eine Eversions-TEA und 4 mal eine TEA/ Patchplastik angewendet, 62 % der Patienten befanden sich im Stadium 1 der Erkrankung, ,65 % erhielten präoperativ eine i.a.DSA der supraaortalen Äste ,100% eine Duplexsonografie und eine CCT; postoperativ fielen insgesamt 12 Intensiv- Pflegetage an sowie eine Revision aufgrund einer Nachblutung. In der Gruppe New Castle befanden sich 68% der Patienten in einem klinischen Stadium 2,es wurde 25 mal offen thrombendarteriektomiert, davon 21 mal mit Direktnaht verschlossen und 4 mal mit Patchplastik, alle Patienten erhielten präoperativ eine CT- Angiografie und eine Duplexsonografie; postoperativ fiel 1 Intensivpflegetag an und eine Revision wegen Nachblutung. Die Morbiditäts-/ Mortalitätsrate betrug in beiden Gruppen 0%. Betriebswirtschaftlich wurden bei einer Liegedauer von durchschnittlich 10 Tagen in Frankfurt 1 tatsächliche Kosten von 2768.96€ pro Patient ermittelt, in New Castle,bei einer Liegedauer von durchschnittlich 5 Tagen und einer differenten Kostenstruktur von 2510.56 €. In der Gruppe Frankfurt 2 wurde 11mal eine TEA mit Patchplastik und 9 mal eine Eversions-TEA durchgeführt, alle Patienten erhielten präoperativ eine Duplexsonografie und eine CCT , postoperativ fielen insgesamt 6 Intensivtage an, es wurde nicht revidiert, die Morbiditäts-/Mortalitätsrate lag ebenfalls bei 0%. Durch Einführung eines klinischen Behandlungspfades wurde also die Liegedauer in Frankfurt um 40 % reduziert sowie die tatsächlichen Kosten auf 2384.41€ pro Fall und damit im Mittel um 14 % gemindert. Schlussfolgerung Unter DRG-Bedingungen trägt daher die Anwendung eines klinischen Behandlungspfades in der Carotischirurgie zu einer Verbesserung der Erlössituation ohne Qualitätseinbuße bei.
Free riders play fair
(2012)
After the demise of the social contract theory, the argument from fair play, which employs the principle of fair play, has been widely acknowledged as one of the most promising ways of justifying political obligation. First, I articulate the most promising version of the principle of fair play. Then, I show that free riders play fair, that is, that their moral fault lies not in unfairness but in the violation of a rule by appealing to the example of three-in-a-boat. Finally, I conclude that even the most promising version is false because those who have accepted benefits from a social cooperative scheme do not owe an obligation of fair play.
The correspondence between the terminology used for querying and the one used in content objects to be retrieved, is a crucial prerequisite for effective retrieval technology. However, as terminology is evolving over time, a growing gap opens up between older documents in (long-term) archives and the active language used for querying such archives. Thus, technologies for detecting and systematically handling terminology evolution are required to ensure "semantic" accessibility of (Web) archive content on the long run. As a starting point for dealing with terminology evolution this paper formalizes the problem and discusses issues, first ideas and relevant technologies.
The KADoNiS (Karlsruhe Astrophysical Database of Nucleosynthesis in Stars) project is an online
database (www.kadonis.org) for cross sections relevant to the s-process and the p-process.
The first version was an updated sequel to the previous Bao et al. [1] compilations from 1987
and 2000 for (n; g) cross sections relevant to Big Bang and s-process nucleosynthesis. The first
update, KADoNiS v0.2, was published in 2006 [2]. It contained mainly Maxwellian averaged
(n; g) cross sections relevant to the s-process, and some experimental charged particle induced
reaction relevant to the p-process. After that a second update was presented in 2009 [3].
Recently, we started to collect and review all existing experimental data relevant for p-process
nucleosynthesis and to provide a user-friendly database based on the KADoNiS framework. The
p-process part of the KADoNiS database is currently being extended and will include all available
experimental data from (p; g), (p;n), (p;a), (a,g), (a;n) and (a; p) reactions in or close to the
respective Gamow window.
Is the digital future a blessing for philologists, especially those working the vast area of Germanic Languages & Literatures? Or does it rather come with problems that jeopardize philology, in the Germanic and the broader scope? This paper sets out to explore the status quo (1.) of digital source material in Germanic philology, ranging from medieval manuscripts to 21st century e-books and their, at times, highly restricted availability to the scientific community. Do we really face a quantum leap in terms of open access, or is this leap rather confined to those only who pay the exorbitant fees specialist libraries charge for the use of their rare manuscript and book collections? How about Google Books (2.)? Are we in danger of neglecting everything that is (still) missing there? And what is in it for the German scholar? Can we believe that in some years’ time we will be able to get our hands on every source text we desire within seconds since it is only a click away? This paper critically assesses the process and progress of the digitization of mankind’s written records (3.), focusing on problems to be overcome by e.g. medievalists wishing to consult certain source material. This is illustrated by means of the example of how it is not yet possible consult certain materials related to the Franciscan preacher Berthold von Regensburg († 1272). A short concluding summary (4.) highlights perspectives for further thinking and discussion.
We perform a detailed study of the adjoint static potential in the pseudoparticle approach, which is a model for SU(2) Yang-Mills theory. We find agreement with the Casimir scaling hypothesis and there is clear evidence for string breaking. At the same time the potential in the fundamental representation is linear for large separations. Our results are in qualitative agreement with results from lattice computations.

The Gribov mode in hot QCD
(2017)
Der vorliegende Text zeigt die Position einer Autodidaktin bzw. Dilettantin: Zwar habe ich mich schon früher in verschiedenen Lehr-Settings mit Digital Humanities auseinandergesetzt, vor dem Sommersemester 2020 spielte die digitale Lehre aber kaum eine Rolle, es sei denn man zählt die Nutzung unterschiedlicher universitärer e-Learning-Portale (Moodle, Ilias etc.) zur Terminplanung und Materialbereitstellung schon dazu. Gerade weil ich mich als Nachzüglerin begreife, die behelfsmäßig einiges nachzuholen hatte und nur ansatzweise die lange schon existierenden Praktiken und Diskurse kannte, empfand ich den offenen Brief "Verteidigung der Präsenzlehre" als unfair, nicht nur gegenüber denjenigen, die sich jetzt notgedrungen versuchten zu professionalisieren, vor allem aber unfair gegenüber denjenigen, die schon lange intensiv und didaktisch kompetent digitale Elemente erprobt und zu Szenarien des Blended Learning entwickelt haben: Eine Diagnose, die die komplette Ersetzung der Präsenzlehre als latent schon geplante Sparmaßnahme unterstellt und eine Intervention, die aus diesem negativen Szenario heraus die hergebrachte Präsenzlehre mit ihren vielen Lebenslügen meint verteidigen zu müssen, schien mir unangebracht, weil von den elaborierten hochschuldidaktischen Perspektiven in Richtung "digitaler Präsenz" und von den Chancen für die Forschung keine Rede war. Und: Der Aufwand und die technische Implementierung von digitaler Lehre kann, sofern die Qualitätssicherung ernst genommen wird, nicht als Sparmaßnahme durchgehen. Eher im Gegenteil!
We discuss the present collective flow signals for the phase transition to quark-gluon plasma (QGP) and the collective flow as a barometer for the equation of state (EoS). A study of Mach shocks induced by fast partonic jets propagating through the QGP is given. We predict a significant deformation of Mach shocks in central Au+Au collisions at RHIC and LHC energies as compared to the case of jet propagation in a static medium. Results of a hydrodynamical study of jet energy loss are presented.
Was charakterisiert Universität? Welchen Leitbildern folgten – und folgen – Hochschulreformen? Unter diesen zentralen Fragestellungen den bundesrepublikanischen Diskurs im Spannungsfeld von universitärem Selbstverständnis und gesellschaftspolitischen Anforderungen näher zu beleuchten, seine Entwicklung zu dokumentieren und zu deuten, war Anliegen der Tagung „Zwischen Idee und Zweckorientierung. Vorbilder und Motive von Hochschulreformen seit 1945“.[1] Die im Rahmen des Forschungskollegs „Wissenskultur und gesellschaftlicher Wandel“ von den Teilprojekten Soziologie und Neuere Geschichte an der Johann Wolfgang Goethe-Universität Frankfurt vom 2. bis zum 4. März 2006 ausgerichtete Veranstaltung wurde von der Fritz Thyssen Stiftung für Wissenschaftsförderung unterstützt. ...
Fragestellung: Die meniscofemoralen Ligamente (MFL) ant. (Humphry) und post. (Wrisberg) begleiten inkonstant das hintere Kreuzband vom lateralen Meniskus zur medialen Femurkondyle, sie üben eine Außenmeniskusstellfunktion aus. Bisherige Literatur gibt eine stark variierende Inzidenzrate der MFL an, die durch eine hohe Fallzahl von untersuchten Kniegelenken in dieser Arbeit verifiziert werden soll.
Methoden: 122 frische, unversehrte Kniegelenke von 31 männlichen und 30 weiblichen Leichen des Sektionsgutes der Rechtsmedizin Frankfurt, wurden auf Inzidenz und Morpholgie von ant. und post. MFL untersucht, ein ventraler (n.Souryal) und dorsaler Nochweitenindex (NWI) erstellt sowie eine morphologische Typisierung der vorhandenen ant. und post. MFL vorgenommen
Ergebnisse: 96% der Kniegelenke zeigten ein oder beide MFL, davon post. MFL in 82% und ant. MFL in 58%. Beide Ligamente in beiden Knien einer Leiche kamen zu 33% vor. Statistisch wurde keine Korrelation zwischen Alter, Geschlecht, Seite und der Inzidenz der Ligamente gefunden. vNWI: w 0,22; m 0,24. dorsaler NWI: w 0,26; m 0,28. Einteilung des post. MFL (Wrisberg): Typ I Strang, Typ II Fächer, Typ III kein meniskaler Ansatz.
Schlussfolgerungen: Die Inzidenz und damit auch klinische Relevanz beider MFL liegt höher als bisher angenommen, z.B. in der Beurteilung von Knie-MRTs als falschpos. Rupturen oder in der klinischen Untersuchung als Abschwächung einer hinteren Schublade. Die Typisierung zeigt einen Zusammenhang des post. MFL mit einem dritten Kreuzband auf: nach Evolution des aufrechten Ganges und damit weniger Rotation im Kniegelenk bildet es sich zurück.
Syntactic coindexing restrictions are by now known to be of central importance to practical anaphor resolution approaches. Since, in particular due to structural ambiguity, the assumption of the availability of a unique syntactic reading proves to be unrealistic, robust anaphor resolution relies on techniques to overcome this deficiency. In this paper, two approaches are presented which generalize the verification of coindexing constraints to de cient descriptions. At first, a partly heuristic method is described, which has been implemented. Secondly, a provable complete method is specified. It provides the means to exploit the results of anaphor resolution for a further structural disambiguation. By rendering possible a parallel processing model, this method exhibits, in a general sense, a higher degree of robustness. As a practically optimal solution, a combination of the two approaches is suggested.
An anaphor resolution algorithm is presented which relies on a combination of strategies for narrowing down and selecting from antecedent sets for re exive pronouns, nonre exive pronouns, and common nouns. The work focuses on syntactic restrictions which are derived from Chomsky's Binding Theory. It is discussed how these constraints can be incorporated adequately in an anaphor resolution algorithm. Moreover, by showing that pragmatic inferences may be necessary, the limits of syntactic restrictions are elucidated.
Coreference-Based Summarization and Question Answering: a Case for High Precision Anaphor Resolution
(2003)
Approaches to Text Summarization and Question Answering are known to benefit from the availability of coreference information. Based on an analysis of its contributions, a more detailed look at coreference processing for these applications will be proposed: it should be considered as a task of anaphor resolution rather than coreference resolution. It will be further argued that high precision approaches to anaphor resolution optimally match the specific requirements. Three such approaches will be described and empirically evaluated, and the implications for Text Summarization and Question Answering will be discussed.
In the last years, much effort went into the design of robust anaphor resolution algorithms. Many algorithms are based on antecedent filtering and preference strategies that are manually designed. Along a different line of research, corpus-based approaches have been investigated that employ machine-learning techniques for deriving strategies automatically. Since the knowledge-engineering effort for designing and optimizing the strategies is reduced, the latter approaches are considered particularly attractive. Since, however, the hand-coding of robust antecedent filtering strategies such as syntactic disjoint reference and agreement in person, number, and gender constitutes a once-for-all effort, the question arises whether at all they should be derived automatically. In this paper, it is investigated what might be gained by combining the best of two worlds: designing the universally valid antecedent filtering strategies manually, in a once-for-all fashion, and deriving the (potentially genre-specific) antecedent selection strategies automatically by applying machine-learning techniques. An anaphor resolution system ROSANA-ML, which follows this paradigm, is designed and implemented. Through a series of formal evaluations, it is shown that, while exhibiting additional advantages, ROSANAML reaches a performance level that compares with the performance of its manually designed ancestor ROSANA.
In the last decade, much effort went into the design of robust third-person pronominal anaphor resolution algorithms. Typical approaches are reported to achieve an accuracy of 60-85%. Recent research addresses the question of how to deal with the remaining difficult-toresolve anaphors. Lappin (2004) proposes a sequenced model of anaphor resolution according to which a cascade of processing modules employing knowledge and inferencing techniques of increasing complexity should be applied. The individual modules should only deal with and, hence, recognize the subset of anaphors for which they are competent. It will be shown that the problem of focusing on the competence cases is equivalent to the problem of giving precision precedence over recall. Three systems for high precision robust knowledge-poor anaphor resolution will be designed and compared: a ruleset-based approach, a salience threshold approach, and a machine-learning-based approach. According to corpus-based evaluation, there is no unique best approach. Which approach scores highest depends upon type of pronominal anaphor as well as upon text genre.
Die gegenwärtige Entwicklung innovativer Medizintechnologien erweist sich als ein lebendiges wie gespenstisches Geschehen. Sie erzeugt therapeutische Handlungsspielräume für Krankheitsformen, die vormals als nicht mehr behandelbar galten und sich jeglicher kurativen Einflusssphäre entzogen. Gleichermaßen berühren sich mit der Effizienz der Eingriffsmöglichkeiten, Regionen des Ungewissen über die Wirkmechanismen des jeweiligen technologischen Verfahren. Die hieraus resultierenden Deutungsherausforderungen betreffen sowohl die beteiligten Ärztinnen, Patienten und Angehörige (Peter, Funcke 2013). Als exemplarisch für ein solche gleichzeitige Hervorbringung medizinisch hoffnungsvoller sowie vertraute Erfahrungsweisen verunsichernder Technologien wird in diesem Vortrag die neurochirurgische Behandlungsmethode der tiefen Hirnstimulation (THS) als Gegenstand soziologischer Betrachtung thematisiert. Die THS ist ein reversibler Eingriff, bei welchen vermittels stereotaktischer Techniken impulsgebende Elektroden tief ins Hirn eingesetzt werden. Die je nach diagnostizierten Störungsbild anvisierten Zielregionen werden im Anschluss an die Implantation elektronisch stimuliert. Medikamentös nicht mehr zu behandelnde Symptome können reduziert werden. Trotz ihrer infolge zahlreicher klinischer Studien nachgewiesenen Effizienz bildet die THS weiterhin eine kontroverse Behandlungsmethode, die sowohl unter medizinischen als auch ethischen Prämissen diskutiert wird. Einerseits kristallisiert sich am Nicht-Wissen über die spezifischen Wirkungszusammenhänge die Notwendigkeit einer erweiterten klinischen Forschung. Andererseits verweist das Auftreten nicht-intendierter Nebenwirkungen, die von Patient_innen, wie deren Angehörigen als individuelle Persönlichkeitsveränderungen wahrgenommen werden, auf die Relevanz einer interpretativen Bestimmung der subjektiven Erfahrung von Seiten der Betroffenen. Der Beitrag nimmt sich zum Ziel, entlang einer empirischen Fallstudie, in der eine Patientin vor und nach der Operation begleitet wurde, und vermittelt durch eine ereignistheoretische Konzeption, auf die Auslegungsbedingungen für betroffene Patient_innen im Zuge der neurotechnologischen Anwendung der THS aufmerksam zu machen.
The discourses on textuality and literacy that can be observed in the Kyot-Excursus in 'Parcival' by Wolfram von Eschenbach and in the Magnetbergerzählung of the 'Reinfried von Braunschweig' will serve here as examples in an attempt to historicize textual models. My essay will focus on how the limits of textuality could be defines within those 13th-century aristocratic orders of knowledge to which court literature can provide an access. What emerges within this context are concepts and ideas that lie beyond the scope of modern scholarly systems; these narratives indicate a way of dealing with textuality and literacy that, rather than referring to the textual discourse, may remain instead on the phenomenal surface of the material or (as if the textual discourse did not exist) may embody implicitly the circumstances that it signifies.
Was die altgermanistische Fachidentität wo nicht zu gefährden droht, da doch neu zu bestimmen nahe legt, das lässt sich am einfachsten unter jenem gängigen Stichwort 'Kulturwissenschaft' fassen, welches überhaupt in den Programm- und Legitimierungdebatten solcher akademischen Fächer eine zentrale Rolle spielt, die man einmal ohne weiteres die Geisteswissenschaften nannte. Dabei scheint durchaus umstritten zu sein, ob mit 'Kulturwissenschaften' ein Bruch mit den Traditionen der Deutschen Philologie angesagt ist oder im Gegenteil deren neuerliche Stabilisierung.
Vom 4. bis 6. April 2013 fand im Schloss Herrenhausen (Hannover) das Colloquium "Nach der Theorie, jenseits von Bologna, am Ende der Exzellenz? Perspektiven der Germanistik im 21. Jahrhundert" statt. Fünfundfünfzig geladene Teilnehmerinnen und Teilnehmer sowie rund sechzig Gäste diskutierten auf Podiumsdiskussionen und abseits davon streitbar und produktiv über die Entwicklungen und Perspektiven der Germanistik.
Die Forschung bediente sich (…) [des Begriffes Schwankroman] im Sinnes eine Gattungsbegriffes, auch wenn sie nicht übersah, daß 'Schwankroman' bei aller Praktikabilität zugleich Ausdruck einer Verlegenheit ist, in welche ursprünglich wohl die ästhetische Norm von der geschlossenen Einheitlichkeit jeder Dichtung, die diesen Namen verdienen soll, geführt hat, einer Verlegenheit nämlich angesichts der offenkundig episodischen Struktur der genannten epischen Großerzählungen, die ihr Zusammengesetztsein aus kurzen, in sich weithin vollständigen Erzähleinheiten kaum je verleugnen. Dieses Dilemma schlägt sich nieder in der Binnenspannung zwischen den beiden Komponenten des Begriffs auf quantitativer, formal-struktureller und kategorialer Ebene: (…)
Einleitung: Lokoregionäre Rezidivtumore der Kopf-Hals-Region können häufig nicht mehr kurativ operativ oder radiotherapeutisch behandelt werden, so dass neue Therapiekonzepte erforderlich sind. Es konnte gezeigt werden, dass statische Magnetfelder (SMF) Tumorwachstum und -angiogenese signifikant beeinflussen und zu einem intratumoralen Ödem führen. Das Ziel der vorliegenden Studie war die Evaluation des Effektes von SMF auf die Permeabilität von Tumorblutgefäßen und die therapeutische Nutzbarkeit in Kombination mit einer konventionellen Chemotherapie.
Methoden: Zellen eines syngenen amelanotischen Melanoms wurden in transparente Rückenhautkammern bei Goldhamstern implantiert. Unter SMF-Exposition von 587 mT wurde fluoreszenzmikroskopisch die Extravasation von rhodaminmarkiertem Albumin zur Errechnung der Gefäßpermeabilität gemessen und intratumorale Leukozyten-Endothelzell-Interaktionen quantifiziert. Für die anschließende Therapiestudie wurden die antitumoralen Effekte einer Kombinationstherapie von Paclitaxel und SMF-Exposition verglichen mit drei Kontrollgruppen (Glucose, Paclitaxel allein, SMF allein; je n=6).
Ergebnisse: SMF führen zu einer signifikanten Erhöhung der Tumorblutgefäßpermeabilität bei unveränderten Leukozyten-Endothelzell-Interaktionen. Die Kombinationstherapie von SMF und Paclitaxel ist – bezogen auf Tumorwachstum und Angiogenese – Monotherapien überlegen.
Schlussfolgerung: Eine SMF-induzierte Steigerung der Gefäßpermeabilität kann die Blut-Tumor-Schranke beeinflussen und somit die Effektivität einer Chemotherapie mit kleinmolekularen Substanzen wie Paclitaxel deutlich steigern. Bei Verwendung von Kopfspulen erscheint eine derartige adjuvante Kombinationstherapie für lokoregionäre Karzinomrezidive der Kopf-Hals-Region besonders geeignet.
Hintergrund: Die studentische Ausbildung sollte sowohl inhaltlich als auch organisatorisch auf qualitativ hohem Niveau durchgeführt werden. Während die Evidenzbasierte Medizin (EbM) auf inhaltlicher Ebene die medizinische Ausbildung optimieren kann, vermag dies auf organisatorischer Ebene das Qualitätsmanagement (QM). Aus diesem Grund führte die Arbeitsgruppe EBM Frankfurt des Instituts für Allgemeinmedizin am Universitätsklinikum Frankfurt am Main ein umfassendes Qualitätsmanagementsystem (QMS) ein.
Methoden: Auf Eigeninitiative einiger Arbeitsgruppenmitglieder wurde mit Unterstützung der Stabsstelle Qualitätsmanagement des Uniklinikums Frankfurt ab Oktober 2002 ein alle Teilbereiche der Arbeitsgruppe umfassendes QMS eingeführt. Unter Führung des QM-Lenkungsteams der Arbeitsgruppe wurden für alle relevanten Prozesse des Lehrbetriebs Ablaufdiagramme, Checklisten, Prozessbeschreibungen und Mindeststandards definiert und eingeführt. Hierbei wurden alle Mitglieder aktiv und kontinuierlich in den Erstellungsprozeß eingebunden.
Ergebnisse: Durch die kontinuierliche Beteiligung aller Mitarbeiter konnte ein allgemein akzeptiertes, lebendiges, effektives und zertifizierbares Qualitätsmanagementsystem eingeführt und aufrechterhalten werden. Wichtiger als eine Zertifizierung erscheint jedoch die kontinuierliche Verbesserung des Lehrbetriebs, die sich in zunehmend besseren Benotungen des curricularen EbM-Seminars (WiSe 2003/04: 2,37 vs. SoSe 2006: 1,54) und effektiver Kursgestaltung bei geringer Personalkapazität wiederspiegelt.
Schlussfolgerung/Implikation: Die Implementierung eines QMS auf freiwilliger Basis ist in Bereichen akademischer Lehre unter Beachtung wichtiger Erfolgsfaktoren mit moderatem Personal- und Sachkostenaufwand möglich und ein effektives Instrument zur Verbesserung der von den Studierenden wahrgenommenen Dienstleistungsqualität.

Despite the great importance of the Latin language in the past, there are relatively few resources available today to develop modern NLP tools for this language. Therefore, the EvaLatin Shared Task for Lemmatization and Part-of-Speech (POS) tagging was published in the LT4HALA workshop. In our work, we dealt with the second EvaLatin task, that is, POS tagging. Since most of the available Latin word embeddings were trained on either few or inaccurate data, we trained several embeddings on better data in the first step. Based on these embeddings, we trained several state-of-the-art taggers and used them as input for an ensemble classifier called LSTMVoter. We were able to achieve the best results for both the cross-genre and the cross-time task (90.64% and 87.00%) without using additional annotated data (closed modality). In the meantime, we further improved the system and achieved even better results (96.91% on classical, 90.87% on cross-genre and 87.35% on cross-time).
The recognition of pharmacological substances, compounds and proteins is an essential preliminary work for the recognition of relations between chemicals and other biomedically relevant units. In this paper, we describe an approach to Task 1 of the PharmaCoNER Challenge, which involves the recognition of mentions of chemicals and drugs in Spanish medical texts. We train a state-of-the-art BiLSTM-CRF sequence tagger with stacked Pooled Contextualized Embeddings, word and sub-word embeddings using the open-source framework FLAIR. We present a new corpus composed of articles and papers from Spanish health science journals, termed the Spanish Health Corpus, and use it to train domain-specific embeddings which we incorporate in our model training. We achieve a result of 89.76% F1-score using pre-trained embeddings and are able to improve these results to 90.52% F1-score using specialized embeddings.
Die Gründerinnen des Arbeitskreises für spätmittelalterliche Wirtschaftsgeschichte Julia Bruch (Köln), Ulla Kypta (Frankfurt am Main) und Tanja Skambraks (Mannheim) luden vom 15. bis zum 16. November zu einer ersten Konferenz mit dem Titel "Neue Methoden der spätmittelalterlichen Wirtschaftsgeschichte" ein. In ihrer Begrüßungs- und Einführungsrede verwies ULLA KYPTA (Frankfurt am Main) auf die Methodenvielfalt in den Wirtschaftswissenschaften und die Schwierigkeiten bei der adäquaten Auswahl und dem sinnvollen Gebrauch derselben innerhalb der Wirtschaftsgeschichte. So bedinge die Anwendung von wirtschaftswissenschaftlichen Modellen immer wieder die Konfrontation mit den empirischen Quellenbefunden. Neben den wirtschaftswissenschaftlichen seien die sozial- und kulturwissenschaftlichen Ansätze ebenfalls in das Methodenspektrum der Wirtschaftshistoriker aufzunehmen. ...
We analyze hadrochemical freeze-out in central Pb+Pb collisions at CERN SPS and LHC energies. Employing the UrQMD hybrid transport model we study the effects of the final hadron/resonance expansion phase on the hadron multiplicities established at hadronization. The bulk meson yields freeze out directly at hadronization whereas the baryon-antibaryon sector is subject to significant alterations, due to annihilation and regeneration processes. We quantify the latter changes by survival factors for each species which are applied to modify the statistical model predictions for the data. The modified SM analysis recovers the hadronization points, which coincide with the recent lattice QCD predictions of the parton-hadron transition line at finite baryochemical potential.
Diagnostische Probleme bei Infektionen in der Intensivmedizin und ihre therapeutischen Konsequenzen
(1983)
In this talk we discuss the effects of the hadronic rescattering on final state observables in high energy nuclear collisions. We do so by employing the UrQMD transport model for a realistic description of the hadronic decoupling process. The rescattering of hadrons modifies every hadronic bulk observable. For example apparent multiplicity of resonances is suppressed as compared to a chemical equilibrium freeze-out model. Stable and unstable particles change their momentum distribution by more than 30% through rescattering. The hadronic rescattering also leads to a substantial decorrelation of the conserved charge distributions. These findings show that it is all but trivial to conclude from the final state observables on the properties of the system at an earlier time where it may have been in or close to local equilibrium.
Spinodal crumbling
(2013)
Extending a previously developed two-phase equation of state, we simulate head-on relativistic lead-lead collisions with fluid dynamics, augmented with a finite-range term, and study the effects of the phase structure on the evolution of the baryon density. For collision energies that bring the bulk of the system into the mechanically unstable spinodal region of the phase diagram, the density irregularities are being amplified significantly. We also present results for the associated clump size distribution.
We discuss the effects of the final hadronic state, in ultra-relativistic nuclear collisions, on hadronic resonance properties and measurable production rates. In particular we will compare our results with recent ALICE data on resonance production. We show that the hadronic phase of the system evolution has a considerable impact on the measured resonance ratios and pT spectra. We also discuss some of the remaining uncertainties in the model and how they may be addressed in future studies.
Mit den vorliegenden Ausführungen wird versucht, das häufig behandelte Phänomen der Verführung an der Rezeption von "Amor und Psyche", dem "artigen Märchen-Histörchen", wie es der spätantike Schriftsteller nennt, an einigen Beispielen aus der Lyrik der frühen Moderne aufzudecken. Wie bekannt, nahm Apuleus die Erzählung in seinem berühmt gewordenen Roman "Der goldene Esel" auf. Die Fabel erzählt, wie die Königstochter Psyche, die ihrer Schönheit wegen mit Venus verglichen wird, den Neid der Göttin herausfordert und dadurch veranlaßt, Psyche an ein Ungeheuer zu verkuppeln. Amor jedoch will Psyche für sich gewinnen und verlangt von Zephir, sie ihm in seinen Palast zu bringen. Psyche verbringt eine Liebesnacht mit Amor, ohne ihn sehen zu dürfen und zu wissen, daß er es ist. Von ihren Schwestern, die sie besuchen, verleitet, will Psyche das angebliche Ungeheuer, für welches Amor gehalten wird, im Schlaf töten. Beim Schein der Lampe erkennt sie den Gott. Er erwacht und verläßt sie. Nach Irrfahrten und bestandenen Prüfungen hilft ihr Amor letztlich doch. Jupiter setzt sich für die Vereinigung beider ein. Psyche wird in den Kreis der Unsterblichen aufgenommen.
Der Beitrag setzt sich zum Ziel, die Traditionen, aktuelle Tendenzen und Aufgaben der Erforschung der historischen deutschen Stadtkanzleisprachen auf dem Territorium Böhmens, Mährens und Schlesiens vorzustellen. Der erste Teil ist dem Phänomen des tschechisch-deutschen Bilingualismus in den böhmischen Ländern gewidmet, im zweiten Teil werden Geschichte und aktuelle Aufgaben der Untersuchung der historischen Kanzleisprachen in unserem Land präsentiert und der dritte Teil zeigt Möglichkeiten einer historiolinguistischen Untersuchung an Beispielen frühneuhochdeutscher Texte der Olmützer Stadtkanzlei.
The QCD phase diagram at finite temperature and density has attracted considerable interest over many decades now, not least because of its relevance for a better understanding of heavy-ion collision experiments. Models provide some insight into the QCD phase structure but usually rely on various parameters. Based on renormalization group arguments, we discuss how the parameters of QCD low-energy models can be determined from the fundamental theory of the strong interaction. We particularly focus on a determination of the temperature dependence of these parameters in this work and comment on the effect of a finite quark chemical potential. We present first results and argue that our findings can be used to improve the predictive power of future model calculations.
n order to reach the desired intensities of heavy ion beams for the experiments at FAIR, SIS18 and SIS100 have to be operated with intermediate charge states. Operation with intermediate charge state heavy ions at the intensity level of about 1011 ions per cycle has never been demonstrated elsewhere and requires a dedicated upgrade program for SIS18 and a dedicated machine design for SIS100. The specific problems coming along with the intermediate charge state operation in terms of charge exchange processes at collisions with residual gas atoms, pressure bumps by ion induced desorption and corresponding beam loss appears far below the typical space charge limits. Thus, new design concepts and new technical equipment addressing these issues are developed and realized with highest priority. The upgrade program of SIS18 addressing the goal of minimum ionization beam loss and stable residual gas pressure conditions has been defined in 2005. A major part of this upgrade program has been successfully realized, with the result of a world record in accelerated number of intermediate charge state heavy ions.

As an alternative production scenario to the so-called g process, the most abundant p nucleus 92Mo may be produced by a chain of proton-capture reactions in supernovae type Ia. The reactions 90Zr(p,g) and 91Nb(p,g) are the most important reactions in this chain. We have measured the first reaction using high-resolution in-beam g-spectroscopy at HORUS, Cologne, Germany, to contribute to the existing experimental data base. So far, we only investigated the high-energy part of the Gamow window and the analysis is still in progress. We plan to study the second reaction in standard kinematics at the FRANZ facility, Frankfurt, Germany. Current developments at FRANZ will be explained in detail.
Die Frage, ob "Literatur als Kampfmittel" Theorie oder Realität in der DDR gewesen ist, lässt sich nicht eindeutig beantworten. Schließlich redet man über 40 Jahre DDR-Regime, in denen es kulturpolitische Zäsuren und Strategiewechsel gegeben hat. Generell gilt: Die Kulturpolitik der DDR war kunstfeindlich. Offiziell gab es keine Zensur, faktisch schon. Die Führung der DDR betrachtete ganz in der Tradition von Stalin und Chruschtschow KünstlerInnen als aktive Kämpfer für den Sozialismus. Der realistische Sozialismus war genreübergreifend die einzig legitime Form. Und man war gewillt, diese offen formulierten Anforderungen an Literaten auch mit Gewalt durchzusetzen. Trotzdem war die offizielle Literaturpolitik das eine, die literarische Praxis das andere. Die Literaturszene im Prenzlauer Berg etwa war erstaunlich autonom und im Aufbau-Verlag erschienen bemerkenswerte Titel. Die Ausbürgerung Biermanns 1976 führte zu einer historisch einmaligen Solidaritätsbewegung und einem Exodus der Ost-Literaten. Sicher ist: Die DDR ist Vergangenheit, aber in ihrer Literatur ist die Erinnerung an Staat und Gesellschaftssystem bewahrt.
Hans-Georg Soldat (Berlin) arbeitete als Literatur-Redakteur beim RIAS in West-Berlin und referierte "Zur Rolle von Westpresse und Rundfunk". Er berichtete, dass DDR-Autoren im RIAS-Literaturprogramm stark vertreten waren. In der DDR unzugängliche Bücher wurden in den RIAS-Besprechungen ausgiebig zitiert, um auf diese Weise die Literatursperre zu unterlaufen. Ein Indiz für die Wirkung dieser Vorgehensweise lieferte die Vorstellung einer DDR-Ausgabe einer sowjetischen Anthologie. Kurz nach der RIAS-Sendung avancierte das Buch vom Ladenhüter zur Bückware. Insgesamt sank jedoch der Stellenwert des Radios.

Poster presentation at 1st International Workshop on Odor Spaces.
Mice are exceptional in their ability to capture their chemical environment, mapping the olfactory world into a basic sensory representation with over one thousand different types of chemical sensors, that is, olfactory sensory neurons (OSNs). OSNs of each type converge in the olfactory bulb onto exclusive distinct physiological areas called glomeruli. The glomeruli constitute the first relay station of olfactory stimulus representation in the mouse brain. Thus, the stimulus induced glomerular input pattern spatially embodies an important part of the sensory representation in the olfactory bulb. Still, topographic organization principles (chemotopy, tunotopy) are under debate. One reason might be that investigation are, due to experimental limitations, only performed on stimuli sets in the size of one hundred odors. But this represents only a tiny snapshot of the vast amount of molecules in the olfactory world and topographic relationships might be disguised in the incomplete representation of molecular receptive ranges (MRR). Therefore we investigated the problem with the MOR18-2 glomerulus as point of reference: First we determined it's MRR. Then, based on a measurement set covering this MRR, we elucidated the topographic embedding. It shows that MOR18-2 is embedded in a hierarchy of patchy tunotopic domains.
We analyze the universal critical behavior at the chiral critical point in QCD with three degenerate quark masses. We confirm that this critical point lies in the universality class of the three dimensional Ising model. The symmetry of the Ising model, which is Z(2), is not directly realized in the QCD Hamiltonian. After making an ansatz for the magnetization- and energy-like operators as linear admixtures of the chiral condensate and the gluonic action, we determine several non-universal mixing and normalization constants. These parameters determine an unambiguous mapping of the critical behavior in QCD to that of the 3d-Ising model. We verify its validity by showing that the thus obtained orderparameter scales in accordance with the magnetic equation of state of the 3d-Ising model.
The objective of this paper is to test the hypothesis that in particular financially constrained firms lease a higher share of their assets to mitigate problems of asymmetric information. The assumptions are tested under a GMM framework which simultaneously controls for endogeneity problems and firms' fixed effects. We find that the share of total annual lease expenses attributable to either finance or operating leases is considerably higher for smaller firms with higher average interest rates and high-growth firms - those likely to face higher agency-cost premiums on marginal financing. Furthermore, our results confirm the substitution of leasing and debt financing for lessee firms. However, we find no evidence that firms use leasing as an instrument to reduce their tax burdens.

Some advances in legal practical reason: for a progressive dialogue with contemporary hermeneutics
(2012)
This paper intends to critically discuss some points of the contemporary thesis concerning constitutional hermeneutics and methodology of law. Once identified some authors and the lines of argumentation affiliated grosso modo to the linguistic turn and rhetoric, as well as the core of the transcendental powers of communication (v.g. N. MacCormick, R. Alexy, K. Günther), the objective is to identify some dialogue with economics and political science, enlightened by recent researches about Hegel-Marx interpretations of social life. Of course the discussion inevitably passes through methodological questions, opposing analytics vs. dialectics, idealistic vs. realists standpoints. In a effort to foment the inclusive dialogue between points of view concerning the concept of law that may create (not necessarily) radical opponents, the lines of conclusion intents to revisit some foundations of Hegelian "method" (so to speak) and intends to give a modest contribution to a more profound analysis of the relations between sein and sollen categories, in order to enrich the discussions about technology and social life, specially the life of the law nowadays.
In this paper I demonstrate the utility of a Values in Design (VID) perspective for the assessment, the design and development of e-democracy tools. In the first part, I give some background information on Values in Design and Value-Sensitive Design and their relevance in the context of e-democracy. In part 2, I analyze three different e-democracy tools from a VID-perspective. The paper ends with some conclusions concerning the merits of VID for e-democracy as well as some considerations concerning the dual tasks of philosophers in assessing and promoting value-sensitive technology design.
A number of pressures on academic libraries imperil the long-term survivability of printed knowledge and heritage materials. Ever-growing volumes of materials, costs of preserving and delivering paper-based research resources, and researchers’ growing demand for source materials in electronic formats all produce strain on our institutions. ...
This lecture is about the history of the "Naier idisher teater" in Riga, the construction process of the building since 1913, the people and organisations that were involved, the theatre opening, playing schedules, companies, cooperation and actors as well as about the intercultural, economic and social environments and activities around the theatre until it was closed forcibly by the German troupes in 1941.
The improvement of accident prevention technology in many fields of social life has spurred new challenges to the doctrinal tools of fault and strict based civil liability in the law of torts. Amid these challenges lies the identification of the proper scope of the respective criteria of liability in a changing factual environment, their suitability as doctrinal tools, as well as their actual application to concrete cases given the amount of information which would be needed to render adequate judgments. Precedents and old laws should be assessed with caution, taking into account the tacit cost-benefit analysis embedded in them, for they may or may not serve the interests of welfare maximization in an environment with constantly renewed accident prevention technology.
[Abstract] Serumspiegel der Immunglobuline bei gesunden Rauchern und Nichtrauchern mittleren Alters
(1993)
In this paper we show an approach to the customization of GermaNet to the German HPSG grammar lexicon developed in the Verbmobil project. GermaNet has a broad coverage of the German base vocabulary and fine-grained semantic classification; while the HPSG grammar lexicon is comparatively small und has a coarse-grained semantic classification. In our approach, we have developed a mapping algorithm to relate the synsets in GermaNet with the semantic sorts in HPSG. The evaluation result shows that this approach is useful for the lexical extension of our deep grammar development to cope with real-world text understanding.
